I'm getting the following error when trying to deploy to a new database:

X 11/14/2013 11:53:51 AM -> An error occurred while creating the stored procedure [dbo].[CreateConstraint].
X 11/14/2013 11:53:51 AM -> SqlException       
X 11/14/2013 11:53:51 AM ->   Incorrect syntax near 'GO'.

Below is the code for the SP (copied from the create procedure section of the DDT), but I can copy/paste into SSMS and the code runs without error.

???

-- Add the parameters for the stored procedure here

@p_cTableName VARCHAR(100) = '',
@p_cConstraintName VARCHAR(4000) = '',
@p_cConstraintExp VARCHAR(4000) = ''
